Michael T. Osterholm, Ph.D., M.P.H., is a prominent public health scientist and a nationally-recognized biosecurity expert in the United States. Osterholm currently holds appointments as the director of the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota, as well as a professor in the School of Public Health, and an adjunct professor in the University of Minnesota Medical School.

From 1975 to 1999, Osterholm served in various roles at the Minnesota Department of Health (MDH), including as state epidemiologist and Chief of the Acute Disease Epidemiology Section from 1984 to 1999. While at the MDH, Osterholm strengthened the departments role in infectious disease epidemiology, notably including numerous foodborne disease outbreaks, the association between tampons and toxic shock syndrome (TSS), and the transmission of hepatitis B and human immunodeficiency virus (HIV) in healthcare workers. Other work included studies regarding the epidemiology of infectious diseases in child-care settings, vaccine-preventable diseases (particularly Haemophilus influenzae type b and hepatitis B), Lyme disease, and other emerging and re-emerging infections.

From 2001 through early 2005, Osterholm, in addition to his role at CIDRAP, served as a Special Advisor to then–HHS Secretary Tommy G. Thompson on issues related to bioterrorism and public health preparedness. In April 2002, Osterholm was appointed to the interim management team to lead the Centers for Disease Control and Prevention (CDC), until the eventual appointment of Julie Gerberding as director.
